Die Neuerung betrifft eine Dichtungsanordnung für Rollenlager, insbesondere einreihige Zylinderrollenlager, mit loser Bordschel'oe, welche aus einer Diohtscheibe aus elastischem, ölbeständigem Material und einem winkelförmigen Befestigungsring aus Blech besteht.The innovation relates to a sealing arrangement for roller bearings, in particular single row cylindrical roller bearings, with loose Bordschel'oe, which consists of a diaphragm made of elastic, oil-resistant material and consists of an angular fastening ring made of sheet metal.
Zuir Schutz der Lager vor Verunreinigungen und um ein Auseinanderfallen von Lpgern mit loser Bordscheibe vor dem Einbau zu vermeiden, irt es erforderlich, eine komplette Einheit mit einer Dicntungsvorrichtung zu bilden.To protect the bearings from contamination and to prevent them from falling apart To avoid lugs with a loose flange before installation, it is necessary to a complete unit with a dicing device form.
Bekannt ist durch das deutsche Gebrauchsmustfcr 1 9^7 758 eine Dichtungsanordnung mit einer mit Zungen versehenen Haltescheibe, welche die Dichtscheibe /on außen her in axialer Richtung durchstoßen und auf deren Innenseite in radialer Richtung umgebogen sind. Weiter ist im US-Patent 2 755 113 das Festlegen des Außenrandes einer Diohtungsvorrichtung mittels in eine Nut einfedernder oder eingepreßter Zungen einer Metallscheibe beschrieben. Das britische Patent 1 104 877 zeigt dagegen das Anpressen einer Kunststoffdichtscheibe mit Hilfe eines am Umfang eines Lageraußenrings festgelegten Winkelrings. Schließlich ist im deutschen Gebrauchsmuster 6 950 530 ein Rollenlager mit loser Bordscheibe dargestellt, bei welchem die Bordscheibe mittels einer Blechkapps am Außenring befestigt ist, wobei ein Ende der Blechkappe in eine umlaufende Nut am Martel des Außenrings eingreift.A sealing arrangement is known from the German utility model 1 9 ^ 7 758 with a retaining washer provided with tongues, which pierce the sealing washer on the outside in the axial direction and onto which Inside are bent in the radial direction. Next is in the US patent 2 755 113 the definition of the outer edge of a diohting device by means of tongues of a metal disc which spring into or press into a groove described. The British patent 1 104 877, however, shows the pressing of a plastic sealing washer with the aid of a on the circumference of a Bearing outer ring specified angle ring. Finally, in the German utility model 6 950 530, a roller bearing with a loose flange washer is shown, in which the flange washer by means of a sheet metal cap on the outer ring is attached, wherein one end of the sheet metal cap engages in a circumferential groove on the Martel of the outer ring.
Keine der in den genannten Vorveröffentlichungen dargestellten Ausführungsformen zeigt eine einfache, billig herzustellende Dichtungsanordnung, die in Verbindung eines Rollenlagers mit loser Bordscheibe eine komplette Einheit bildet.None of the embodiments shown in the cited prior publications shows a simple, inexpensive to manufacture seal arrangement, which in connection with a roller bearing with a loose flange washer forms a complete unit.
Diese Aufgabe wird nach der vorliegenden Neuerung dadurch gelöst, daß ein winkelförmiger Befestigungsring an seinem axialen Schenkel Zungen be-This object is achieved according to the present innovation in that an angular fastening ring on its axial leg tongues loading

sitzt, welche von außen her in axialer Richtung die Dichtscheibe durcnstoßen, dann die lose Bordscheibe am Innen- oder Au&enumfang umfassen undsits, which penetrates the sealing washer from the outside in the axial direction, then enclose the loose flange washer on the inner or outer circumference and
Ein AusfUhrungsbeispiel der Neuerung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben:An execution example of the innovation is shown in the drawing and is described in more detail below:
Die Dichtungsanordnung besteht aus einer Dichtscheibe 1 aus elastischem, ölbeständigem Material und einem winkelförmigen Befestigungsring 2 aus Blech. Der Innenrand 3 der Dichtscheibe 1 gleitet an der Stirnseite des Lagerinnenrings 4 und bildet außerdem zur Bohrung des Innenrings 4 eine Spaltdichtung. Das Befestigen des Außenrandes 5 der Diehtscheibe 1 erfolgt durch den winkelförmigen Blechring 2, dessen axialer Schenkel Zungen 6 besitzt, welche von außen her in axialer Richtung die Diehtscheibe 1 durchstoßen, dsnn dis loss Bcrdschsibs Y sin Unifsr"1 vunf&ssen »wH schließlich iü eine am Mantel des Lageraußenrings 8 angeordnete Nut 9 eingreifen.The sealing arrangement consists of a sealing washer 1 made of elastic, oil-resistant material and an angular fastening ring 2 made of sheet metal. The inner edge 3 of the sealing washer 1 slides on the end face of the bearing inner ring 4 and also forms a gap seal for the bore of the inner ring 4. Attaching the outer edge 5 of the Diehtscheibe 1 is made by the angle-shaped sheet metal ring 2, the axial leg has tongues 6, which from the outside pierced in the axial direction of the Diehtscheibe 1, dsnn dis loss Bcrdschsibs Y sin Unifsr "1 vunf &SEN" wH finally iii one at Engage the casing of the bearing outer ring 8 arranged groove 9.
Die mit der Neuerung erzielten Vorteile bestehen insbesondere darin, daß eine einfach zu montierende, leicht herzustellende Dichtungsanordnung geschaffen wird, die mit einem Lager mit loser Bordscheibe zu einer kompletten Einheit verbunden ist. Durch die Diehtscheibe aus elastischem, ölbeständigem Material wird das Lager wirksam vor Verunreinigung geschützt, durch den winkelförmigen Befestigungsring die Diehtscheibe wie auch die lose Bordscheibe mit dem Lager fest verbunden und lurch den mit etwas Übermaß hergestellten Außenrand der Diehtscheibe schließlich eine ständige radiale Abdichtung zum Gehäuse erreicht.The advantages achieved with the innovation are in particular that created an easy-to-assemble, easy-to-manufacture seal assembly which is connected to a bearing with a loose flange to form a complete unit. Thanks to the plastic washer made of elastic, oil-resistant Material, the bearing is effectively protected from contamination by the angular fastening ring, the dieht washer and the loose flange washer firmly connected to the bearing and made with a little oversize The outer edge of the dieh disk finally achieves a permanent radial seal with respect to the housing.
Die Neuerung ist nicht allein auf das gezeigte Ausführungsbeispiel beschränkt, sondern es sind ohne weiteres konstruktive Abänderungen möglieh. So könnten z. B. die losen Bordscheiben einen axial nach innen sich erstreckenden, in der Bohrung des Lageraußenrings zentrierten Ansatz aufweisen oder am Innenring vorgesehen werden. Außerdem können die Dichtscheiben mit ihrem Innenrand auch radial gleitend zur dichtenden Anlage gebracht werden.The innovation is not limited to the exemplary embodiment shown, but constructive changes are easily possible. So could z. B. the loose flange washers an axially inwardly extending, have centered approach in the bore of the bearing outer ring or be provided on the inner ring. In addition, the sealing washers can also be brought to the sealing contact with their inner edge in a radially sliding manner.
